Book Information: World's Fair Goblin

The thing called Maximus was eight feet tall and matted with hair. It ran amok among the sophisticated, scientific marvels of the Fair, striking stark, cringing fear into the sightseers. The Man Of Bronze battles the brilliant brain that controls the monster - an evil genius capable of creating an army of huge horrors.
